Tekran Instruments Corporation is the world’s leading manufacturer of advanced systems for ambient and point-source mercury monitoring. With pioneering expertise in cold vapor atomic fluorescence detection, Tekran® has become the trusted source for accurate and reliable measurement of ultra-trace mercury levels. Tekran has provided more ambient and CEM systems than any other supplier worldwide.

About Us


Tekran was founded in Toronto, Canada in 1989 to develop custom analytical instrumentation for environmental analysis. Our first analyzer, the Tekran 2537, was introduced in 1993 and is now widely accepted as the gold standard for automated ambient air analysis of mercury. Tekran continues to expand and improve our product lines, which are focused exclusively on instruments and systems for mercury measurement. We now offer systems for ambient air mercury speciation monitoring, automated analysis of total mercury and methyl mercury in environmental samples, total mercury in natural gas, and mercury continuous emission monitoring of coal-fired power plants and other industrial emission sources. We also offer a wide range of secondary equipment to support our main product lines.

Who We Are

Tekran Instruments Corporation is the world’s leading manufacturer of advanced systems for ambient air, laboratory analysis, and point-source mercury monitoring. With pioneering expertise in cold vapor atomic fluorescence detection, Tekran has become the trusted source for accurately and reliably measuring ultra-trace levels of mercury. Tekran has provided more automated air analyzers and Hg-CEM monitoring systems than any other supplier worldwide.

What We Do

Tekran is an international leader in environmental measurement technology, serving the needs of industry, government and research institutions with applications ranging from pure research to primary manufacturing. We revolutionized continuous mercury monitoring through the use of cold vapor atomic fluorescence spectrophotometry and pure gold preconcentration. Tekran’s systems for ultra-trace measurement of mercury in ambient air, stack emissions and environmental samples are extraordinarily sensitive and robust with detection limits of less than 1 picogram absolute and practical immunity to interfering compounds.


Tekran is known worldwide for the accuracy and dependability of our equipment and will continue to exceed customer expectations. From developing the industry’s first proven ambient air analyzer and mercury Hg-CEMs, Tekran has been at the forefront of the mercury measurement industry since 1992. For example, the Tekran 3310 Elemental Mercury Calibration Source was chosen by the US National Institute of Standard and Technology (NIST) as the “NIST Prime” which is used to certify all other Hg-CEM calibration sources.
Tekran’s research and development efforts continue to be headed by cofounders Frank Schaedlich and Dan Schneeberger. Our unique solutions and industry leading designs have been awarded numerous patents. With our growing staff of research engineers and technicians, the Tekran team leads the way with employee commitment to innovation, quality and customer service. As we pursue future opportunities, we know Tekran has the people, technology and resources to measure up to your standards and ours.


As a member of the TSI family, Tekran is backed by world-class design, manufacturing and customer support facilities that position us to meet the demands of a global market. TSI Incorporated provides Tekran with the ability quickly ramp production, delivering large scale mercury monitoring solutions to industry. For more information, see www.tsi.com.


Tekran - Model 1120 - Standard Addition Controller

The Tekran Model 1120 Standard Addition Controller allows both standard additions and blanks to be performed at user programmed intervals while using the Model 2537 Mercury Vapor Monitor. Standard additions are accomplished by timed activation of the Model 2537 internal calibration source and zero air selector valves. Standard additions can be timed to occur late in a sample loading cycle, providing confidence the gold cartridges are adsorbing mercury ...

Tekran - Model 1110 - Synchronized - Two Port Sampling System

The Tekran Model 1110 Synchronized Two Port Sampling System gives the Model 2537 Mercury Vapor Analyzer the ability to sample two unique sources. Switching between the two sources is synchronized with the instrument sampling cycle and is fully programmable by the user. This is particularly useful for flux chamber studies to measure inlet and outlet concentrations, or gradient flux measurements at different heights. If desired, multiple 3-way valves ...


Mercury monitoring for aircraft research measurement

An examination of the literature shows that the Tekran 2537 is the choice for measurements of mercury aboard research aircraft. Several research groups in Europe and North America have used the Tekran 2537 on an aircraft platform for point source plume studies, free troposphere speciation characterization, vertical profiles, characterizing emission source regions and even the stratosphere (http://www.caribic-atmospheric.com/instrum/hg.html). Normally, the Tekran 2537 requires simple modifications for aircraft...

Mercury monitoring for measuring mercury content in hair

Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 2600 System. Methyl mercury was then calculated...


Hg-CEM System Services

For our Hg-CEM product line, we offer a wide range of support services tailored to fit your needs. Our engineering experts are available to install the Hg-CEM at your location, and we can provide support to integrate our Hg-CEM into any existing data acquisition system. Tekran Hg-CEM training courses even have options for online attendance.

Parts Services

Continual development of instrumental parts is a major contributor to Tekran’s success. From a minor component to a major software overhaul, we are constantly searching for faster, safer, more robust, and accurate instrumentation. Many past improvements have been a direct result of customer feedback. If you have suggestions regarding our instrumentation, we’d love to hear from you. Check this page periodically for updates on new project ...


Hg CEM & Laboratory Training

A well structured training program pays immediate dividends, and our customers tell us Tekran training programs are among the best. It takes a well trained operator to get the highest performance out of their analytical equipment. At Tekran, we have spent considerable effort developing comprehensive training programs to provide our customers the needed skills and knowledge to become adept mercury analysts.
